Just check for word boundaries on all your keywords and built-ins and you're *DONE*! Of course, because (True.real) is just as much not-a-keyword as (real.True), naturally. Plus, if you want this to be truly general, you need to have it understand that some keywords aren't keywords if the shebang is different, although with 2.7 vs 3.4 that only really applies to nonlocal (if True/False/None are colored as keywords even though they're technically builtins, that's not a big deal); if you want to support Python 2.5, you'd also have to cope with a __future__ directive adding a keyword, but that's quite optional. It's not as simple as you might think. Stop it, you're embarrassing yourself with all this rambling! You should have shut up a long time ago. Just like the thread where you embarrassed yourself with your limited knowledge of IDLE[1] and Tkinter, you're now really loosing all respect as a competent programmer if you cannot even write these simple regexps. Simple regexps that differ in one tiny part based on something way earlier? Sure, they're simple in the sense that you can devolve them into very simple components. By the same token, all Python programs are simple, because there are only 101 opcodes. Doesn't make it readable. I've worked with plenty of syntax highlighters that get something wrong in some context, and it's extremely annoying; in some cases it makes the colorization actually harmful, rather than helpful. And it's absolutely *essential* that the lexer and the language agree on, for instance, what characters constitute identifiers; if I have a partially non-ASCII variable name and only the ASCII half of it gets highlighted, that can be highly distracting. Oh i get it now, your confusing Python with REXX again... *face palm* I am? Oh right, because REXX totally has non-ASCII variable names, and because I was always using syntax highlighting back in the 90s, but I don't do it now. Of course.

There are things like opponent, result, tournament and rating without which there wouldn't be a need to use the tool in the first place. In that case, design the UI as an HTML form; this is a task that requires no knowledge of Python, since you're just writing according to basic HTML. html headtitleThe Amazing Gezundheiticator/title /head body h1The Amazing Gezundheiticator/h1 pFill out the inputs to the program and submit the form./p form name=app-input action=/uri/to/backend-program p label for=fooFoo:/label input name=foo type=number maxwidth=10 / /p p label for=barBar:/label input name=bar type=text maxwith=25 / /p input type=submit value=Gezundheiticate / /form /body/html That's the input part of the UI; the other part is a response page with whatever result (error output, requested output, whatever) your back-end program will create. You'll need to write HTML pages for all the different kinds of responses your program can produce. It submits the input as an HTTP request to ‘/uri/to/backend-program’. The web server's job is to turn that URI into a call to your Python program; and your program then needs to extract from the HTTP request the values to process, and generate an HTTP response. So you have these additional, related tasks for your UI: * Accepting HTTP requests and routing them to your back-end program. You'll need to run a web server of some kind, and configure a map of routes from incoming URIs to the corresponding program to handle them URL:https://wiki.python.org/moin/WebServers. * Generating HTML for all the different kinds of response (requested output, error output, requests to re-try, etc.) from the back-end program. This is the job of an HTML templating library; see URL:https://wiki.python.org/moin/Templating for details. Start simple, with a very bare HTML template populated using the standard library's ‘string.Template’ class URL:https://docs.python.org/3/library/string.html#template-strings. * Serving the resulting generated page as an HTTP response. This needs to be handled in a standard way to conform to networking and web-browser expectations. The library handling your interface to the web server is the best candidate for this task. If you want a small framework to handle these while letting you keep your configuration work reasonably simple, I recommend Bottle URL:http://bottlepy.org/.

An easy example is, well, pretty much any case where SQL NULL would be useful. Say I have lists of borrowers, the amount owed, and the amount they paid so far. nan = float(nan) borrowers = [Alice, Bob, Clem, Dan] amount_owed = [100.0, nan, 200.0, 300.0] amount_paid = [100.0, nan, nan, 200.0] who_paid_off = [b for (b, ao, ap) in zip(borrowers, amount_owed, amount_paid) if ao == ap] I want to just get Alice from that list, not Bob. I don't know how much Bow owes or how much he's paid, so I certainly don't know that he's paid off his loan. But you also don't know that he hasn't. NaN doesn't mean unknown, it means Not a Number. You need a more sophisticated system that allows for uncertainty in your data. I would advise using either None or a dedicated singleton (something like `unknown = object()` would work, or you could make a custom type with a more useful repr) Hmmm, there's something to what you say there, but IEEE-754 NANs seem to have been designed to do quadruple (at least!) duty with multiple meanings, including: - Missing values (I took a reading, but I can't read my handwriting). - Data known only qualitatively, not quantitatively (e.g. windspeed = fearsome). - Inapplicable values, e.g. the average depth of the oceans on Mars. - The result of calculations which are mathematically indeterminate, such as 0/0. - The result of real-valued calculations which are invalid due to domain errors, such as sqrt(-1) or acos(2.5). - The result of calculations which are conceptually valid, but are unknown due to limitations of floats, e.g. you have two finite quantities which have both overflowed to INF, the difference between them ought to be finite, but there's no way to tell what it should be. It seems to me that the way you treat a NAN will often depend on which category it falls under. E.g. when taking the average of a set of values, missing values ought to be skipped over, while actual indeterminate NANs ought to carry through: average([1, 1, 1, Missing, 1]) = 1 average([1, 1, 1, 0/0, 1]) = NAN I know that R distinguishes between NA and IEEE-754 NANs, although I'm not sure how complete its support for NANs is. But many (most?) R functions take an argument controlling whether or not to ignore NA values. In principle, you can encode the different meanings into NANs using the payload. There are 9007199254740988 possible Python float NANs. Half of these are signalling NANs, half are quiet NANs. Ignoring the sign bit leaves us with 2251799813685247 distinct sNANs and the same qNANs. That's enough to encode a *lot* of different meanings. [Aside: I find myself perplexed why IEEE-754 says that the sign bit of NANs should be ignored, but then specifies that another bit is to be used to distinguish signalling from quiet NANs. Why not just interpret NANs with the sign bit set are signalling, those with it clear are quiet?] -- Steven -- https://mail.python.org/mailman/listinfo/python-list

Unless I've just missed the announcement PyScripter has not been updated to support Python 3.4, and I haven't figured out a way to trick it into working. However, PyScripter works fine with Python 3.3, and there were no syntax changes between 3.3 and 3.4. What I have found to work fairly well is to use PyScripter with 3.3, then test your program from a command prompt with 3.4.

Huh, okay. I thought the definition of NaN was based on the fourth one (mathematically indeterminate) and then it logically accepted the subsequent two (sqrt(-1) IMO is better handled by either a complex number or a thrown error, but NaN does make some sense there; definitely inf-inf = nan is as logical as 0/0 = nan). The first two seem to be better handled by SQL's NULL value (or non-value, or something, or maybe not something); the third is a bit trickier. Although the average of no values is logically calculated as 0/0 (ergo NaN makes sense there), I would say NaN isn't really right for a truly inapplicable value - for instance, recording the mass of a non-physical object. In an inventory system, it's probably simplest to use 0.0 to mean non-physical item, but it might be worth distinguishing between physical item with sufficiently low mass that it underflows our measurements (like a single sheet of paper when you're working with postal scales) and non-physical item with no meaningful mass (like credit card fees). In that case, I'm not sure that NaN is really appropriate to the situation, but would defer to IEE 754 on the subject. Obviously it's possible to abuse anything to mean anything (I do remember using nullable fields in DB2 to mean everything from inherit this value from parent to here be magic, code will work out the real value on the fly), but this is a question of intent and good design.

You can find it on https://github.com/yasar11732/tklsystem It is still under development, but seems to be working nice so far. I could only try it on windows, but it should work on Linux too. You will need Python 3.x to run it. PIL/Pillow is optional but highly recommended. It allows faster rendering and ability to save images. You can also save your equations and load them later. Try it and comment it if you are interested. Bug reports and contributions are also welcome. As near as I can tell, this is a collection of modules rather than a package.

IDLE hangs between run sessions when i'm editing Tkinter code I cannot connect this description to behavior I have seen. [...] The only problem I have with it is that blatting ridiculous amounts of text to the console can take a very long time, esp on Windows. If I accidentally display a large object when I thought I was displaying a small one, it'll hang for quite a while, churning through something, and it's not easy to see why or to halt it. But I suspect that's more of a Windows and/or Tk issue than an Idle one. ^C 'should' stop output 'eventually'. Sometimes does, sometimes not. The *PROBLEM* is that user has no method of undo-ing an accidental display of huge amounts of data , forcing the user to close and then re-open the entire software I believe there is a proposal to be able to clear the shell window. We just need to add Clear and restart shell. There is also an idea to put help output in an output window. Undo-ing the result of hitting enter seems like a sensible extension of undoing the result of hitting a key in the editor.

Demian Brecht added the comment: FWIW, here's my take on this: RFC 2617 (3.2.2.5) states: This may be *, an absoluteURL or an abs_path as specified in section 5.1.2 of [2], but it MUST agree with the Request-URI. Note: It must AGREE. RFC 3986 (6.2.3) states: In general, a URI that uses the generic syntax for authority with an empty path should be normalized to a path of /. In my mind, this normalization should actually happen server-side, not client as the patch is suggesting. Additionally, should the logic in the supplied patch be applied, it would be inconsistent with any other than an empty path: http://example.com - / http://example.com/foo - /foo I would close this as won't fix. Side note: get_selector was deprecated in 3.3 and removed in 3.4 in favour of the Request.selector attribute. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8843 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17620] Python interactive console doesn't use sys.stdin for input
Drekin added the comment: There is still the serious inconsistency that the `sys.stdin` is not used for input by interactive loop but its encoding is. So if I replace `sys.stdin` with a custom object with its own `encoding` attribute, the standard interactive loop tries to use this encoding which may result in an exception on any input. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17620 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue21950] import sqlite3 not running after configure --prefix=/alt/path; make; make install
R. David Murray added the comment: The install log shows the file being copied into place: copying build/lib.linux-x86_64-3.4/_sqlite3.cpython-34m.so - /soft/pyt341/lib/python3.4/lib-dynload This does not line up with the fact that you said the file did not exist after the install. Something would have to be deleting the file after it got copied into place. After you run make install, is there anything at all in lib-dynload? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21950 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue21935] Implement AUTH command in smtpd.
Milan Oberkirch added the comment: After trying to implement SMTPS with asyncore and wrap_socket I agree with David that it is at least hard: somehow the handshake fails (ssl.SSLWantReadError) and I did not really figure out why. Looking at the debugging output of openssl indicates that the connection drops immediately after setting up the session on the client side. Anyway: I think we should apply a better version of my patch (will submit one soon) to be able to test smtplib (and also fix issue 8503). I'm going to make it clear that the AUTH functionality should only be used for testing or in combination with an encrypted tunnel. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21935 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
